Many of the comments are about the event as a whole, but I'd like to commend the author for the day 1 puzzle, which I think is very cleverly written. Many people (including myself) use these as an opportunity to try out learning a new language, and the first puzzle does a good job of making sure you know enough basic operations for some of the puzzles coming up.

It's faster to just paste the input into your favorite editor, and massage it gently until it is a literal in the language you're using. No parsing necessary.

Eric, the author, says he won't accept any puzzle submissions because of attribution and legal issues. This seems like the wrong outcome for people who want to make the site better but don't want credit, compensation, or attribution. Has anyone seen a site using an IP assignment agreement which is the equivalent of "take my work, I don't want credit, and it's just for your site"? The Creative Commons CC0 license come…

If you want to help, why not ask the people running the site what you can do to help? Do you actually want to help, or do you want to make puzzles? Or do you just want to discuss a perceived problem that may or may not exist?

> Many people (including myself) use these as an opportunity to try out learning a new language I hadn't thought about that! I'll take this as an opportunity to learn Rust!

Checking back in - have you done it, is it going OK?

I can't do it when the puzzles come out (too late in UK) but I've really enjoyed Rust so far and I got my 10 stars so far.

Results are really nice, and match and enums etc. really make the language nice.

Rust really has taken many of the best parts of Python, functional paradigms, and lower level languages, and the compiler errors - being warned about missing branches in matches! I'm hoping that finishing 2019 with Rust will lead to more in 2020!

Learning new environments can be painful so it’s good it starts off easy. I’m trying to solve them with Swift Playgrounds on the iPad, for example. And I can’t figure out how to create a simple text file for the data.

I use pastebin raw and get stuff from web requests sometimes rather than local files.
